Abstract

The invention relates to a supercharged internal combustion engine, preferably a diesel engine, provided with a series connection of a compressor (9) of screw rotor type and a turbo compressor (5). The screw rotor compressor (9) is connected to the pressure side (6) of the turbo compressor and is provided with a capacity regulating means (10) actuated at a predetermined working condition to change the screw rotor compressor (9) to work as an expander for cooling the combustion air of the engine (1) at high engine speed.
